    Area of Science:

    • Optoelectronics
    • Chemical Sensing
    • Materials Science

    Background:

    • Accurate detection of high hydrogen concentrations is critical for safety and industrial processes.
    • Existing hydrogen sensors may face limitations in sensitivity, stability, or cost-effectiveness for specific applications.

    Purpose of the Study:

    • To propose and experimentally validate a novel dual-cavity microstructure fiber optic hydrogen sensor.
    • To demonstrate the sensor's capability for detecting high hydrogen concentrations (10-30% H(2)).
    • To investigate the sensor's performance characteristics, including response time, repeatability, reliability, and temperature effects.

    Main Methods:

    • Fabrication of a dual-cavity microstructure using a splicer, comprising an inner air-cavity and a collapsed photonic crystal fiber cavity.
    • Deposition of an evaporated platinum/tungsten oxide (Pt/WO(3)) film onto the microstructure.
    • Utilizing a three-beam interference model for theoretical simulation and experimental verification.
    • Testing the sensor's response time, repeatability, reliability, and performance across varying hydrogen concentrations and temperatures.

    Main Results:

    • The dual-cavity fiber optic sensor successfully detects high hydrogen concentrations (10-30% H(2)).
    • Theoretical and experimental investigations confirmed the sensor's compensation function against light source fluctuations and fiber loss.
    • The sensor exhibits a rapid response time of 1 minute, along with good repeatability and reliability.
    • Temperature variations were found to have a negligible impact on the sensor's response within the 10-30% H(2) range.

    Conclusions:

    • The proposed dual-cavity microstructure fiber optic sensor offers a promising, cost-effective solution for high hydrogen concentration detection.
    • The sensor's design provides inherent stability and a miniature footprint.
    • The demonstrated performance, including fast response and temperature insensitivity in the target range, highlights its practical applicability.
